Answer:
28.1 mph
Explanation:
The force of friction acting on the car provides the centripetal force that keeps the car in circular motion around the curve, so we can write:
(1)
where
is the coefficient of friction
m is the mass of the car
g = 9.8 m/s^2 is the acceleration due to gravity
v is the maximum speed of the car
r is the radius of the trajectory
On the snowy day,
So the radius of the curve is
Now we can use this value and re-arrange again the eq. (1) to find the maximum speed of the car on a sunny day, when . We find:
Answer:
Electrons jump between energy levels, absorbing and releasing energy as they are jumping between energy levels. The energy given off corresponds to different frequencies of light. If the light is visible, we see these frequencies as different colors.
